Each time the HF Gateway was activated, a test report appeared here.
The test reports and audio files referred to in the text are listed at the bottom of this page and can be downloaded for immediate viewing/listening or for saving for future review. Please note that these files are copyright Steve Richards..

TEST T02: Report exchange formal net
A test in which stations on both HF and Echolink used the Gateway to intercommunicate. The Gateway was using voice-recognition squelch and there were periods of control on both HF and VoIP.

1.
G0DUB/P on 80m working AE2EE on Echolink.
G4KUJ controlling on HF.
This is an interesting clip of QRP station G0DUB/P acting as a station out in the field requesting to exchange information with an Echolink station. This clip demonstrates how a station on HF can satisfactorily control the net. Even though the frequency is heavily congested, the voice recognition squelch performs satisfactorily. The end-of-transmission bleep can also be heard. AE2EE is working at the far end of a repeater chain.

T02R01.WAV (1.2MB)
2.
G4PGZ working GW0VMZ, both on Echolink.
G4KUJ controlling on HF.
Another good demonstration of how the full net can be controlled effectively by an HF NCS. Note the voice recognition squelch sometimes being held open by the heavy off-frequency HF stations.

T02R02.WAV (706KB)
3.
G4PGZ working GW0VMZ, both on Echolink.
This is the same exchange as in clip 2. but as recorded on HF, allowing a comparison to be made as experienced by the various participants.

T02R03.WAV (857KB)
4.
G8OJQ working G4KUJ, both on HF, then GW0VMZ on Echolink.
G4HPE controlling at the Gateway.
A good example of one station working firstly on HF then Echolink.
Recorded on HF at G4PGZ
T02R04.WAV (1.4MB)
5.
HP1/OE5CEN HF Gateway as heard on Echolink.
This short clip demonstrates an NCS using the Panama HF Gateway – sadly not the participating station we were hoping for but good DX anyway!
Recorded on Echolink at G4HPE
T02R05.WAV (235KB)
6.
HP1/OENCEN HF Gateway as heard on HF
This is a slightly longer version of clip 5., but this time as heard on HF in the UK. This demonstrates that it should be quite possible for an HF station in Europe to work an HF station in Central America, using both Gateways bridged by Echolink. The audio seems quite workable.
Recorded on HF at G4PGZ
T02R06.WAV (350KB)
7.
HP1/OE5CEN working AE2EE as heard on Echolink.
G4HPE controlling at the Gateway.
Recorded on Echolink at G4HPE (889KB)
T02R07.WAV (889KB)
8.
HP1/OE5CEN working AE2EE on Echolink.
This is the same exchange as in clip 7. but this time as heard on HF in Europe. Notice that there is a degree of fading on the HF signal caused by the propagation effects.
Recorded on HF at G4PGZ
T02R08.WAV (866KB)
9.
VU2RBI working G4HPE, both on Echolink.
G4KUJ controlling on HF.
Recorded on HF at G4PGZ
T02R09.WAV (1.1MB)
10.
VU2RBI on Echolink working GI7THH on HF.
G4HPE controlling at the Gateway.
GI7THH was a variable signal – the Gateway supervisor had to manually switch the system at times. Communication was marginal due to occasional weak signal strengths and interference, but despite this the message got through.

3.
ZS6BUU on Echolink working MM3UJL/P on 80m.
This is a particularly interesting contact, as it demonstrates a station in South Africa satisfactorily exchanges traffic with a low-power portable station in the field in Scotland.

9.
9H1RA on Echolink working GW0VMZ on 80m.
This is a telling exchange – the station in Malta had very poor propagation and was struggling to take part in the exercise. The Gateway enabled this. 9H1RA was using a handheld to a local UHF repeater which was linked to Echolink and thus to the IRESC conference server.
